DÍAZ1 & S. BLAIR HEDGES2 1Museo Nacional de Historia Natural de Cuba. Apartado Postal 2349, La Habana 2, CP 10 200. E-mail: [email protected] 2Department of Biology, 208 Mueller Lab, Pennsylvania State University, University Park, PA 16802, USA. E-mail: [email protected] Abstract The genus Aristelliger comprises seven species of which six inhabit the West Indies, and one occurs in Central America and satellite islands. For the first time, the genus is reported from Cuba, and a new species (Aristelliger reyesi sp. n.) is described from that island. The new taxon has affinities with the smaller species of the genus (subgenus Aristelligella): A. expectatus, A. cochranae, and A. barbouri. It differs from them in color pattern and other morphological characters. Key words: Reptiles, Aristelligella, West Indies, Península de Hicacos, Varadero Introduction The genus Aristelliger has seven species, of which only one (A. georgeensis Bocourt) occurs in Central America and satellite islands. Two species (A. expectatus Cochran, and A. lar Cope), inhabit Hispaniola; one species occurs on Navassa Island (A. cochranae Grant); two species (A. barbouri Noble and Klingel, and A. hechti Schwartz and Crombie) are found in the Bahamas; and one species (A. praesignis Barbour) occurs in Jamaica, surrounding cays, Cayman Islands, and Swan Islands (Schwartz and Henderson, 1991; Bauer and Russell, 1993a-f; Lynxwiler and Parmerlee, 1993). Additional species are in the process of being described (S. B. Hedges, in prep.). The genus has not previously been recorded from Cuba. The following combination of characters (among others) are present in Aristelliger: 1) small granular scales on most of the body surface; 2) fragile skin; 3) a supraciliar scale modified as a tiny spine; 4) all digits clawed; 5) subdigital lamellae undivided; 6) “friction pads” (sensu Cochran, 1933) on three fingers and two outer toes, or only in one digit of each extremity, depending on the species group (see below); 7) eyes with vertical pupil; 8) one egg per clutch; 9) presence of hemipenial bones (Kluge, 1982); 10) presence of parafrontal bones (Bauer and Rusell, 1989; Gamble et al., 2008); and 11) croaking calls. Gamble et al. (2008) found strong support for a close relationship between Aristelliger and the North African genus Quedenfeldtia, and suggested its inclusion in the family Sphaerodactylidae. There are two recognized groups of species, defined as subgenera by Hecht (1952). The smaller species: A. cochranae, A. barbouri, and A. expectatus (subgenus Aristelligella), are 46−63 mm SVL, have lateral postmentals in contact with the median line of mental scale, and friction pads on three fingers and two outer toes. A second group contains the larger members: A. georgeensis, A. hechti, A. lar, and A. praesignis (subgenus Aristelliger). They are 83−135 mm SVL and have 1−3 median postmentals and friction pads on one finger and one toe (Schwartz and Henderson, 1991). On 30 May 2007 the senior author identified some reptiles photographed by Ernesto Reyes at the Nature Preserve of Varahicacos, Península de Hicacos, Western Cuba. Surprisingly, some of his photos depicted what, undoubtedly, was a gecko of the genus Aristelliger. Soon thereafter several specimens were collected at Accepted by S. Carranza: 6 Jan. 2009; published: 6 Mar. 2009 31.

    CONSERVATION OF SOUTH AFRICAN TORTOISES WITH EMPHASIS ON THEIR APICOMPLEXAN HAEMATOZOANS, AS WELL AS BIOLOGICAL AND METAL-FINGERPRINTING OF CAPTIVE INDIVIDUALS By Courtney Antonia Cook THESIS submitted in fulfilment of the requirements for the degree PHILOSOPHIAE DOCTOR (Ph.D.) in ZOOLOGY in the FACULTY OF SCIENCE at the UNIVERSITY OF JOHANNESBURG Supervisor: Prof. N. J. Smit Co-supervisors: Prof. A. J. Davies and Prof. V. Wepener June 2012 “We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature, and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours they move finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other nations caught with ourselves in the net of life and time, fellow prisoners of the splendour and travail of the earth.” Henry Beston (1928) ABSTRACT South Africa has the highest biodiversity of tortoises in the world with possibly an equivalent diversity of apicomplexan haematozoans, which to date have not been adequately researched. Prior to this study, five apicomplexans had been recorded infecting southern African tortoises, including two haemogregarines, Haemogregarina fitzsimonsi and Haemogregarina parvula, and three haemoproteids, Haemoproteus testudinalis, Haemoproteus balazuci and Haemoproteus sp.

  • Independent Evolution of Sex Chromosomes in Eublepharid Geckos, a Lineage with Environmental and Genotypic Sex Determination

Eyelid geckos (Eublepharidae) are of particular interest, as they encompass species with both environmental and genotypic sex determination. We identified for the first time the X-specific gene content in the Yucatán banded gecko, Coleonyx elegans, possessing X1X1X2X2/X1X2Y multiple sex chromosomes by comparative genome coverage analysis between sexes. The X-specific gene content of Coleonyx elegans was revealed to be partially homologous to genomic regions linked to the chicken autosomes 1, 6 and 11. A qPCR-based test was applied to validate a subset of X-specific genes by comparing the difference in gene copy numbers between sexes, and to explore the homology of sex chromosomes across eleven eublepharid, two phyllodactylid and one sphaerodactylid species. Homologous sex chromosomes are shared between Coleonyx elegans and Coleonyx mitratus, two species diverged approximately 34 million years ago, but not with other tested species. As far as we know, the X-specific gene content of Coleonyx elegans / Coleonyx mitratus was never involved in the sex chromosomes of other gecko lineages, indicating that the sex chromosomes in this clade of eublepharid geckos evolved independently.

Com- University of New Mexico, Albuquerque, NM 87131, USA and Santa Fe Institute, 1399 Hyde parative studies of lizard reproduction to date have usually considered life-history Park Road, Santa Fe, NM 87501, USA, 3School components separately. Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size.

    ANNALS OF THE TRANSVAAL MUSEUM ANNALE VAN DIE TRANSVAAL-MUSEUM- < VOL. 30 30 JUNE 1976 No. 6 THE BURROWING GECKOS OF SOUTHERN AFRICA, 5 (REPTILIA: GEKKONIDAE) By W.D. HAACKE Transvaal lvIllseum, Pretoria (With four Text-figures) ABSTRACT This study deals with the entirely terrestrial genera of southern African geckos and is published in five parts in this journal. In this part the phylogenetic and taxono­ mic affinities of these genera based on pupil shape and hand and foot structure are discussed. PHYLOGENETIC AND TAXONOMIC AFFINITIES In his classification of the Gekkonidae, Underwood (1954) placed six South African genera into the subfamily Diplodactylinae. These genera, i.e. Cho!ldrodac~ylus, Colopus, Palmatogecko, Rhoptropus, Rhoptropella and Ptmopus were supposed to share a peculiar variant of the straight vertical pupil which he called Rhoptropus-type. He notes that all of them occur in "desert or veldt" and appear to be adapted to the special conditions of South Africa. He further states that "Such a number of genera with several peculiar forms of feet in such a restricted area is somewhat surprising". At that time all except Rhoptropuswere considered to be monotypic genera. Since then two more species of Ptmopus and also the terrestrial, obviously related genus Kaokogecko have been described. In the present paper a special study has been made of the ground­ living, burrowing genera, which excludes Rhoptropus and Rhoptropella. Although it has been pointed out that the classification of the Gekkonidae according to the form of the digits (Boulenger, 1885) and the shape of the pupil (Underwood, 1954) is unsatisfactory (Stephenson, 1960; Kluge, 72 1964 and 1967) the possibilities of these characters as taxonomic indicators were reinvestigated in the genera in question and related forms.

Caribbean Herpetology, 62, 1–8. DOI: 10.31611/ch.62 Abstract Croaking Lizards (Aristelliger) are some of the largest geckos occurring in the New World, but knowledge of their basic biology remains limited. Here we present a dietary account of Aristelliger. Our results augment existing data by provid- ing new dietary records for seven of the nine species of Aristelliger. The first dietary records are reported for three of these species (A. barbouri, A. expectatus, and A. hechti). We report lithophagy, frugivory, seed dispersal, and ontogenet- ic variation in the diet of Aristelliger and the first instance of molluscivory in the genus. In total, 22 items were added to the dietary records of various species of Aristelliger with nine items being new to the genus. Keywords: Caribbean, frugivory, gecko, lithophagy, molluscivory. Introduction Aristelliger is a genus of vocal sphaerodactylid geckos that are distributed throughout the West Indies and sporadically along Central America’s Atlantic coast and some satellite islands (Hecht 1952; Schwartz & Henderson 1991; Bauer & Russell 1993).
